Off-Grid Solar PV

Experienced Solar PV Design & Installation

We’ve been installing solar PV since 2010 and have been trusted installers on some amazing projects.

Introduction to Solar PV


Solar PV panels are extremely versatile and adaptable. At The Greener Group, we have installed hundreds of solar PV systems throughout the UK for a range of clients from a range of sectors.

Suited to both domestic and commercial-scale installations, solar PV has been rapidly deployed in the UK and is an ideal solution for those looking to generate their own green energy.

We have an increasing portfolio of happy customers who have adopted off-grid solar PV systems installed by our fully trained and accredited team.

Off-Grid Solar PV Systems

An off-grid Solar PV system is a stand-alone renewable energy system that is not connected to the National Grid and stores energy using batteries.

It is an ideal solution for properties that don’t currently have a connection to the National Grid as it is completely self-reliant, acquiring this connection can be very expensive, making generating your own green energy an attractive alternative. As well as homes, it is suitable for many different types of properties, including sheds, caravans, holiday homes, and narrowboats.

The size of the system you’ll need to install will depend on how much energy you require to power your property. We will design a bespoke system tailored to your exact energy requirements by undertaking a detailed assessment of how much energy you require based on factors such as average consumption and pattern of usage.


Frequently Asked Questions

Understanding how an off-grid PV system works, how it can benefit your property and how it pays for itself over the years can sometimes be perplexing. Don’t fear, the FAQ section below should help answer some of those questions.

If you don’t find the answer you’re looking for please contact one of the team who would be happy to help.


Solar PV

A solar PV system works by converting the sun’s energy into electricity. This electricity is then used to
supply a building or sent to the grid for use elsewhere.

A solar PV system will reduce the amount of imported electricity a property requires, in turn reducing

What is off-grid solar PV suitable for?

Off-grid solar PV is ideal for homes that are not connected to the mains electricity supply. They are also suitable for sheds and outbuildings, caravans, holiday homes and even narrowboats.

Why install off-grid solar PV?

Installing an off-grid solar PV system is an ideal solution for those looking to generate 100% green energy. It is also perfect for those living in houses that aren’t connected to the mains electricity. The cost of setting up a grid connection can be extremely high, making an off-grid solar PV system a more affordable and green option.

Will I generate enough energy to completely power my house?

Before installation, a detailed report is carried out to determine your power requirement. Based on this information we will then design and install an off-grid system that will meet this exact requirement, enabling you to power your home completely disconnected from the mains electricity supply.

Many installations include a back-up generator which will be able to provide the power requirements in the rare occurrence that the solar PV system is unable to.

How much will a solar installation cost?

In terms of the initial outlay required for solar PV system installations, The Greener Group currently offer a
number of financial and funding packages, designed for renewables – which can help you achieve
your green objective.

Do I need planning permission?

In most cases, planning permission is not required to install a solar PV system. However, there are some exceptions, those looking at a solar PV installation for a listed building, building with a conservation order, or located in a National Park/ Area of outstanding natural beauty should check with the local council.

Where does a solar PV system work best?

A solar PV system works best where the panels receive the most amount of sun. So a large South facing roof is
ideal. The fewer obstructions (trees or other buildings) between the panels and the sun the better. However, East and West systems still produce a good yield benefiting from the morning and evening sun. The further South a system is located the more sunlight it will receive. The UK has a fairly consistent level of sunlight so we can predict likely PV generation with a good degree of confidence, where it is located!

Are they easy to maintain and how long do they last?

Solar PV systems are designed to last for over 20 years. The panels come with 20-year performance warranties.
With no moving parts, a PV system is easy to maintain. An annual or bi-annual service, clean and health check is recommended.

Will I receive any Grant or Rebate?

Some local authorities may be offering grants. Unfortunately, an off-grid solar PV system would not qualify for the Smart Export Guarantee (SEG).

Insurance Backed Workmanship Warranty

The Greener Group strives to provide high quality and reliable installation, regardless of the size of the project. To back this up we offer a two-year workmanship guarantee.

To give our clients total peace of mind all our installations are backed by a third party warranty. Should the worst happen to The Greener Group and we go out of business, GDGC will honour the workmanship warranty

The Workmanship Guarantee Scheme has been designed to provide domestic consumers with insurance protection in the event an Installer ceases to trade and therefore is unable to honour their outstanding workmanship obligations. The protection comes in the form of an Insurance Backed Guarantee Policy. This service is offered to domestic installations up to a maximum of £50,000.

Deposit Protection

Installers that are part of the scheme may also have the facility to be able to protect a Deposit payment that has been paid to the Installer with insurance protection for a period of up to 60 days. The Deposit Protection is capped at a maximum of 25% of the contract value, up to a maximum Deposit amount of £5,000.

Product Warranties

Each product or technology we install comes with its own product warranty. This varies from product to product and can often be extended where required.

For more information on any aspect of the warranties, The Greener Group or any of our suppliers offer please contact us.


To ensure your solar panels are working as efficiently as possible, it is important to keep up to date on your servicing and maintenance. We recommend that you book in for a service and health check every 12 months and can tailor our packages to suit your needs.

      • Check panels are free of dirt and debris
      • Inspect all mounting systems and fixings, ensuring they are safely secured
      • Check for shading issues since the installation
      • Check DC cables are secure
      • Check modules are free from dirt/leaves, bird droppings etc
      • Check the roof integrity
      • Test of current devices to ensure they are in good working order
      • Inspect electrical connections for corrosion and ensure they are secure
      • Check enclosures are secure and the IP rating is maintained
